3 Claims. 3

This invention relates to safety razors and is particularly directed toan improved form 01' razor employing a ribbon-type blade.

The principal object of this invention is to provide a novel form ofsafety razor employing a ribbon-type blade in which supply and take-upcoils are mounted on a carrier for attachment to therazor head as aunit.

Another object is to provide a razor of this type having supply andtake-up spools positioned below a razor head together with clamp meansabove the head which is movable to hold the ribbon blade on a blade seatprovided on the top surface of the head.

Another object is to provide a novel form of take-up spool for a ribbonblade razor.

Other objects and advantages will appear hereinafter.

Referring to the drawings:

Figure 2 is a front elevation partly broken away taken substantially inthe direction 22 as in dicated in Figure l.

Figure 3 is a sectional side elevation partly broken away takensubstantially on the lines 3-2 as shown in Figure 2.

Figure 'lis a side elevation; Figure 8 is front elevation partly broken away;Figure 9 is a sectional side elevation showing the manner of attachmentof the carrier to the razor head; and Figure 10 is an explodedview-illustrating themanner of assembly of the carrier and razor head.

Referring to the drawings, the safety razor shown in Figure 1 andgenerally designated It may be provided with a handle ll having an inclined head l2 rigidly secured at its upper end.- A cover it overliesthe head I! and may be provided with a central sleeve ll slidablymounted within a recess I. The sleeve is interiorly threaded to receivethe upper end of the rod it which extends upwardly through the handleand which is secured to the knob il. Rotation of the knob il serves tomove the cover It with respect to the razor head 12. The forward edge 68of the razor head l2 may be provided with the usual comb teeth, and apair of upwardly projecting guide pins 69 are mounted at opposite endsof the comb i8. Additional upwardly projecting guides 20 are provided onthe razor head, and the upper surface of the razor head extending fromthe comb l8 to the location of the projecting guides 20 constitutes aseat surface 25 for a blade. The surface 2' is interrupted by openings22 which extend through the razor head.

A ribbon blade 23 of metallic flexible material is provided with asharpened portion 26 along one edge thereof. The blade 23 extends from asupply shell 25 to a take-up shell 26, and the blade is coiled withinthe shells as shown in Figure 5. The blade 23 extends outwardly from theshell 25 through an aperture 21 and extends over the blade seat 2i onthe upper surface of the razor head l2. The blade then extends into theaperture 39 in the take-up shellzt, and is wound on a spool or reel 38provided with an exposed knob 3i. Ratchet means comprising a resilientpawl 32 formed from the body of the shell 26 engages ratchet teeth 33formed on the reel 38 to prevent reverse movement of the ribbon blade 23with respect to the blade seat 2|. The supply shell 25 may be providedwith a cap 25aand the take-up shell 26 has an opening in'one end toreceive a central bearing 38a provided on the reel 38. The extreme endsof the blade seat 2| are rounded as shown at 28 to avoid overstressingthe ribbon blade as it enters and leaves the blade seat.

Means are provided on the razor head for holding the shells 25 and 26,and as shown in the drawings this means includes a pair of spring clips-29 and 30. The shell 25 is held within the spring clip 29 and maintainedagainst displacement while the shell 26 is similarly supported andconfined by the spring clip 30. Preferably a leader portion on theribbon blade having an unsharpened edge is provided so that the shells25 and 26 can be installed within the spring clips 29 and 30 withoutdanger oi. cutting the fingers of the user. When the ribbon blade 23 isinstalled in position on the blade seat 2! the knob 3| on the take-upspool 38 is turned to bring the sharpened edge 24 into operativeposition on the blade seat 2!. The handle knob I1 is then rotated tobring the cover-i3 downwardly with respect to the razor head and toengage the forward end 34 thereof with the ribbon blade 23 in a order tohold it tightly against the seat 2 I. when through use a fresh'portionedges 2! of the blade seat 2 I.

3 edge 24 of the blade becomes dull of the blade may be brought intoservice by first lifting the cover I! and then winding the knob 2| towithdraw an unused length of ribbon blade 23 irom the supply spool 2|.The cover is then returned to clamping position by actuation of thehandle knob l'l. Movement of the cover It with respect to the head i2may be guided by means of the lateral pins 35 extending through thevertical slots 36 provided in the side walls of the cover. The forwardlyextending portions 31 of the cover side walls are effective as guardsfor shielding the sharpened edge 24 of the blade 23 between thelocations where it emerges from the shells 25 and 26 and locations whereit contacts the curved the sharpened when the supply of ribbon bladecome exhausted the shells 25 and 26 may be discarded and new shellsconnected by a fresh blade installed.

In the modified form f my invention as shown in Figures '7 to 10inclusive, the razor handle Ii, head l2, cover i3. knob i1, shells 25,26 and blade 2! may take the form illustrated and described in theforegoing figures. This modification differs primarily in that theshells are mounted in spaced position on a removable carrier 50 whichmay be attached to the underside of the razor head i2. The carrier 50includes a spaced pair of curved gripping elements i and 52 adapted tosupport and hold the shells 25 and 26 respectively, together with acentral bridge element 53 extending therebetween. A pair of fingers 54are mounted under the razor head i2 and attached thereto by means of therivets 55. These fingers resiliently clamp the bridge 53 against side ofthe razor head I2 and disassembly is prevented by means of engagement ofa protuberance 56 on the ends of the fingers adapted to enter therecesses 51 provided on the bridge 53. The fingers are. sufficientlyresilient to permit installation and removal of the bridge in adirection transverse of the length of the blade 23.

The operation of this form of my invention is substantially the same asthat previously described. The cover i3 is moved downwardly to clamp theribbon blade 23 against the blade seat 2 I. When the supply of sharpenedribbon blade has been exhausted the shells 25 and 26 may be disposed ofas before and new shells installed on the carrier. If desired thecarrier and shells 23 has be-' theundercanbeformedasasingleimiaandinthiscase the entire unit would bediscarded and a new one supplied.

Having fully. described my invention, it is to be understood that I donot wish to be limited to the details herein set forth, but my,invention is of the full scope of the appended claims.

I claim:

l. A safety razor comprising in combination: a razor head having anupwardly facing blade seat, a flexible ribbon blade on theseat, one endof the blade being coiled in a supply shell and the other being securedto a take-up reel; a spacer member extending between the shell andtake-up reel and adapted to maintain them in spaced relationship; meanson the razor head for releasably securing the spacer member to the underside thereof; the shell, reel, blade and spacer member being insertableas a unit into operative position on the razor head to position theblade on said seat.

, 2. A safety razor comprising in combination: a razor head having anupwardly facing blade seat, a flexible ribbon blade on the seat, one endof the blade being coiled in a supply shell and the other being securedto a take-up reel; a spacer member extending between the shell andtake-up reel and adapted to maintain them in spaced relationship; springfingers on the underside of the head for releasably securing the spacermember thereto; the shell, reel, blade and spacer member beinginsertable as a unit into operative position on the razor head toposition the blade on said seat. 1

3. In a safety razor, the combination of a handle having a head providedwith an upwardly facing blade seat; a flexible ribbon blade extendingacross said seat, one end of the blade being coiled in a supply shelland' the other being secured to a take-up reel; a spacer member extendinunder the razor head and adapted to maintain the shell and reel inspaced relationship; the shell, reel, blade and spacer member beinginsertable as a unit into operative position on the razor head toposition the blade on said seat, and a releasable clamping membermovably mounted over the head and adapted tc move downwardly to maintainthe ribbon blade in position on said blade seat.
